Solar Calculator

Solar System Calculator for Nigeria

Enter the appliances you use, how long you use them each day, and select the appliances you want your battery to power after sunset. The calculator will estimate the solar panels, inverter and battery you may need.

1. Add Your Appliances

Choose a Quick Start Pick a home or business setup to get started. You can change the appliances, power and usage afterward.

For each appliance, enter the quantity and how many hours you use it per day. Tick Battery backup if you want that appliance to continue working after the sun goes down.

2. Tell Us About Your Solar Needs

We use 4.5 hours as a starting estimate for Nigeria. This is also called Peak Sun Hours.
Choose how long the selected backup appliances should keep running when there is no solar power, such as at night or during a power outage.
Not sure which to choose? Lithium is planned at 85% usable capacity, Gel at 60%, and Tubular at 50%. The selected type is used for both the battery calculation and the matching battery price recommendation.
Not sure? Choose the voltage that matches your inverter and battery bank. As a simple guide: 12V = small systems, 24V = medium systems, 48V = larger home systems. The exact voltage must match the equipment you buy.
Choose the type you expect to buy. This also helps the price recommendation show the matching inverter category.
Choose the controller type you want the system recommendation and price matching to use.
Panel technology does not change the basic wattage calculation; it records the type you prefer for the equipment recommendation.
This selects the physical panel size used when converting the required solar array into a panel count.
Simple explanation

Understand Your Solar Recommendation

You do not need to know the technical terms before using this calculator. We calculate them from the appliances and usage you enter.

Why did the calculator give me this result?

Your appliance choices and usage determine the daily energy and the maximum power the system may need. We then estimate the inverter, battery and solar panels needed for that plan.

Learn the technical details

Your result is a planning estimate. Actual equipment can change with appliance ratings, starting power, sunlight, battery specifications, shading, wiring and installation conditions.

Solar Calculator FAQs

Common questions about using our solar system calculator for homes and small businesses in Nigeria.

What does the SolarPriceNG solar calculator help me work out?

It estimates solar panel capacity, inverter size and battery storage from the appliances you enter, how long you use them and which appliances you want to run from the battery after sunset.

Is this calculator accurate enough to buy a solar system?

It is a planning estimate, not a final engineering design. Actual system size can change because of appliance ratings, starting or surge power, battery type, inverter efficiency, shading, weather, wiring and how the system is used. A qualified installer should confirm the final design before you buy.

What does battery backup mean?

Battery backup is the time your selected backup appliances are expected to keep running from the battery when solar production is no longer supplying the load, such as after sunset or during a power outage.

How many solar panels do I need in Nigeria?

There is no single number for every home. The required panel capacity depends on your daily energy use, battery recharge needs, peak sunlight hours, panel wattage and system losses. Use the result from this calculator as a starting point and check the exact panel configuration before installation.

Why can my solar system cost more than the calculator result?

The calculator focuses on system sizing. A real installation can also require cables, mounting structures, breakers, surge protection, earthing, changeover equipment, labour, transport and other site-specific materials.

Can I check current solar equipment prices after calculating?

Yes. Your result can be saved as a SolarPriceNG plan on your device. You can then continue to the equipment cost tool or check the Solar Prices in Nigeria database to compare available products and price ranges.
